Description

Technical Field

[0001] The present application relates to the technical field of steel strip slitting, and particularly to a steel strip slitting device. Background Art

[0002] A steel strip refers to a conveyor belt made of carbon steel as the traction and carrying member of a belt conveyor, and can also be used for bundling goods; during the finishing process of the steel strip, according to the needs of various metal or mechanical products in different industrial sectors for industrial production, the steel strip is cut into corresponding width dimensions by a slitting device to produce a narrow and long steel plate.

[0003] Currently, the commonly used slitting device includes a frame. A first support seat is fixedly arranged at one end of the frame, and a second support seat is slidably arranged at the other end of the frame. A moving component for driving the second support seat to move is arranged on the frame. A support plate is arranged between the first support seat and the second support seat. A slitting component for slitting the steel strip is arranged at one end of the support plate. The slitting component includes a slitting reel rotatably connected to both the first support seat and the second support seat. The slitting reel is detachably connected to the second support seat. A cutter disc and a spacer disc are arranged on the slitting reel, and the cutter disc and the spacer disc are distributed at intervals. When replacing the cutter disc and the spacer disc, the moving component pushes the second support seat to move, so that the second support seat is separated from the slitting reel, and the operator replaces the cutter disc and the spacer disc according to the required width of the steel strip.

[0004] Regarding the above related technology, the inventor believes that using the moving component to push the second support seat to move to replace the cutter disc and the spacer disc and adjust the distance between the cutter discs has a low replacement efficiency. Summary of the Invention

[0005] In order to facilitate the adjustment of the distance between the cutter discs, the present application provides a steel strip slitting device.

[0006] A steel strip slitting device provided by the present application adopts the following technical solutions:

[0007] A steel strip slitting device includes a frame, a slitting mechanism for slitting the steel strip, and a conveying mechanism for conveying the steel strip; the slitting mechanism includes a plurality of slitting components arranged in sequence, and adjacent two slitting components are rotatably connected; each slitting component includes a cutter head for cutting the steel strip, an installation shaft is fixedly arranged on the cutter head, and a first rod and a second rod are rotatably arranged on the installation shaft; connection mechanisms are arranged at both ends of the slitting mechanism, the connection mechanisms are symmetrically arranged, each connection mechanism includes a cutting knife for cutting the steel strip and two connecting rods rotatably connected to the cutting knife, one connecting rod is rotatably connected to the first rod, the other connecting rod is rotatably connected to the second rod, a driving mechanism for driving the slitting mechanism to cut the steel strip and the conveying mechanism to convey the steel strip is arranged on one cutting knife, a connecting shaft is fixedly arranged on the other cutting knife, the connecting shaft is rotatably connected to the frame, and an adjusting mechanism for adjusting the distance between the cutter heads is arranged on the driving mechanism.

[0008] By adopting the above technical solution, the frame provides an installation position for the slitting mechanism and the transmission mechanism, and also provides support for the steel strip. The slitting mechanism is used for slitting the steel strip, and the conveying mechanism is used for conveying the steel strip to the slitting mechanism; the slitting mechanism is composed of a plurality of slitting components, wherein the cutter head is used for cutting the steel strip, and the distance between adjacent two cutter heads can be adjusted by the rotation of the first rod and the second rod; the driving mechanism is used for driving the slitting mechanism to rotate to cut the steel strip and driving the conveying mechanism to convey the steel strip, and the adjusting mechanism is used for the distance between the cutter heads; the driving mechanism drives the slitting mechanism and the adjusting mechanism to operate, so as to adjust the distance between the cutter heads, and the operation is simple and convenient.

[0009] Optionally, the driving mechanism includes a rotating component for driving the cutter head and the cutting knife to rotate. The rotating component includes a rotating tube rotatably connected to the frame and a sliding rod passing through and slidingly connected to the rotating tube. One end of the sliding rod is rotatably connected to the cutting knife, a motor is arranged at one end of the rotating tube, a first ratchet is fixedly arranged on the cutting knife, a first pawl is rotatably arranged on the sliding rod, and the first ratchet and the first pawl are used for controlling the rotation of the cutting knife when the motor rotates forward. A first resetting member for resetting the first pawl is arranged on the sliding rod.

[0010] By adopting the above technical solution, the rotating assembly is used to mount the strip splitting mechanism on the frame. When the motor rotates forward, the motor drives the rotating tube to rotate. The rotation of the rotating tube drives the sliding rod to rotate, thereby driving the first ratchet pawl to rotate. At this time, the first ratchet wheel and the first ratchet pawl are engaged, and the rotation of the first ratchet pawl will drive the first ratchet wheel to rotate, thereby driving the connecting mechanism and the strip splitting mechanism to rotate, and performing strip splitting on the steel strip. When the motor rotates in reverse, the first ratchet pawl rotates along the inner wall of the first ratchet wheel under the action of the first reset member and does not drive the first ratchet wheel to rotate. The cooperation of the first ratchet wheel and the first ratchet pawl realizes strip splitting of the steel strip when the motor rotates forward, and when the motor rotates in reverse, the strip splitting mechanism stops operating.

[0011] Optionally, a receiving groove is formed in the sliding rod. One end of the first ratchet pawl is located in the receiving groove, and the first reset member is located in the receiving groove. The first reset member includes a telescopic rod hinged to the first ratchet pawl. The telescopic rod is hinged to the sliding rod, and a spring is arranged on the telescopic rod.

[0012] By adopting the above technical solution, when the first ratchet wheel and the first ratchet pawl are engaged, one side of the first ratchet pawl abuts against the side wall of the receiving groove. When the motor rotates forward, the first ratchet pawl drives the first ratchet wheel to rotate. When the motor rotates in reverse, the side wall of the first ratchet wheel presses on the first ratchet pawl, causing the first ratchet pawl to rotate. Under the action of the spring and the telescopic rod, the first ratchet pawl rotates along the inner wall of the first ratchet wheel and does not drive the first ratchet wheel to rotate, enabling strip splitting of the steel strip when the motor rotates forward.

[0013] Optionally, the adjusting mechanism includes a mounting seat fixedly connected to the frame and a moving member sleeved on the sliding rod. The mounting seat is rotatably connected to the rotating tube, and the moving member is rotatably connected to the first ratchet wheel. A second ratchet wheel is rotatably arranged at one end of the mounting seat, and a second ratchet pawl is rotatably arranged on the rotating tube. The second ratchet wheel and the second ratchet pawl are used to control the movement of the moving member when the motor rotates in reverse. A second reset member for resetting the second ratchet pawl is arranged on the rotating tube, and a transmission member for transmitting the rotation of the second ratchet wheel to the moving member is arranged on the frame. The transmission member causes the moving member to slide along the length direction of the sliding rod.

[0014] By adopting the above technical solution, when the width of the required steel strip needs to be changed, the distance between the cutter disks can be adjusted by the adjusting mechanism; when the motor rotates in reverse, the rotation of the motor drives the rotating pipe to rotate, causing the second pawl to rotate. At this time, the second pawl meshes with the second ratchet wheel, and the rotation of the second pawl will drive the second ratchet wheel to rotate. Under the action of the transmission member, the rotation of the second ratchet wheel will drive the moving member to move, and the movement of the moving member will drive the connecting mechanism to move, causing the first rod and the second rod to rotate, thereby adjusting the distance between the cutter disks; when the motor rotates forward, the side wall of the second ratchet wheel squeezes the second pawl, causing the second pawl to rotate. Under the action of the second reset member, the second pawl rotates along the inner wall of the second ratchet wheel and does not drive the second ratchet wheel to rotate, realizing the adjustment of the distance between the cutter disks when the motor rotates in reverse.

[0015] Optionally, the transmission member includes a fixing plate fixedly connected to the frame, a transmission shaft rotatably connected to the fixing plate, and a first bevel gear fixedly connected to the transmission shaft. A second bevel gear meshing with the first bevel gear is fixedly arranged on the second ratchet wheel. The transmission member further includes a transmission rod and an adjusting rod rotatably connected to the transmission rod. The transmission rod is fixedly connected to the transmission shaft, and the adjusting rod is rotatably connected to the moving member.

[0016] By adopting the above technical solution, the transmission member is used to transmit the rotation of the second ratchet wheel to the moving member. When the second ratchet wheel rotates, the second bevel gear rotates. Since the first bevel gear and the second bevel gear mesh, the rotation of the second bevel gear will drive the first bevel gear to rotate, causing the transmission shaft to rotate, thereby causing the transmission rod to rotate. The rotation of the transmission rod will drive the adjusting rod to move, thereby driving the moving member to move, realizing the movement of the moving member.

[0017] Optionally, a limiting groove is formed on the moving member, and a limiting ring fixedly arranged on the first ratchet wheel and embedded in the limiting groove and rotatably connected to the limiting groove is provided.

[0018] By adopting the above technical solution, the limiting ring is embedded in the limiting groove, realizing the connection between the moving member and the first ratchet wheel. When the moving member moves, it can drive the first ratchet wheel to move, avoiding the separation of the moving member and the first pawl and affecting the use of the slitting mechanism.

[0019] Optionally, the conveying mechanism includes two rollers rotatably connected to the frame. The two rollers are driven by gears, and one of the rollers is belt-driven by the connecting shaft.

[0020] By adopting the above technical solution, when the motor rotates forward, the connecting shaft rotates, and the rotation of the connecting shaft drives one of the rollers to rotate. The two rollers are driven by gears, and the rotation of one roller drives the other roller to rotate. The steel belt is located between the two rollers, and the rollers generate frictional force with the steel belt during rotation, thereby causing the steel belt to move, completing the transmission of the steel belt, realizing the linkage between the slitting mechanism and the transmission mechanism, and saving the use cost of the slitting mechanism.

[0021] Optionally, a sliding groove is formed in the inner wall of the rotating tube, and a sliding block is fixedly arranged on the side wall of the sliding rod and is embedded in the sliding groove and slidably connected to the sliding groove.

[0022] By adopting the above technical solution, the sliding block is embedded in the sliding groove. When the rotating tube rotates, the rotating tube drives the sliding block to rotate, causing the sliding rod and the rotating tube to rotate synchronously, preventing the sliding rod from rotating in the rotating tube and affecting the use of the steel belt slitting equipment.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When adjusting the distance between the tool holders, the motor rotates in reverse. The reverse rotation of the motor causes the rotating tube to rotate. At this time, the second ratchet wheel and the second ratchet pawl are engaged, and the first ratchet pawl rotates along the inner wall of the first ratchet wheel. The rotation of the rotating tube drives the second ratchet wheel to rotate without causing the tool holders to rotate. Under the action of the transmission member, it drives the moving member to slide along the length direction of the sliding rod. Since the limiting ring is embedded in the limiting groove, the movement of the moving member drives the first ratchet wheel to move, thereby driving the cutting tool to move, causing the first rod and the second rod to rotate. Therefore, the distance between the tool holders can be adjusted without disassembling the tool holders, improving the working efficiency of the steel belt slitting device;

[0025] 2. When slitting the steel belt, the motor rotates forward. When the motor rotates forward, the rotating tube rotates. At this time, the first ratchet wheel and the first ratchet pawl are engaged, and the second ratchet pawl rotates along the inner wall of the second ratchet wheel. The first ratchet pawl drives the first ratchet wheel to rotate, thereby driving the connecting mechanism and the slitting mechanism to rotate. The steel belt is slit by the rotation of the tool holders and the dividing knives, realizing the linkage between the slitting process and the adjustment process;

[0026] 3. The connecting shaft and the rollers are driven by a belt. When the motor rotates forward, the connecting shaft rotates, thereby driving the rollers to rotate to drive the steel belt, realizing the synchronous operation and linkage of the slitting mechanism and the transmission mechanism, and reducing the manufacturing cost.

Detailed implementation manners

[0035] The following further describes the present application in detail Figure 1-7 with reference to the accompanying drawings.

[0036] An embodiment of the present application discloses a steel strip slitting device. Refer to Figure 1, A steel strip slitting device includes a frame 1, a storage mechanism 2 for storing the steel strip 11, a slitting mechanism 3 for slitting the steel strip 11, and a transmission mechanism 4 for driving the steel strip 11. During use, the steel strip 11 is placed on the storage mechanism 2, and the steel strip 11 is transmitted to the slitting mechanism 3 through the transmission mechanism for cutting to complete the slitting process of the steel strip 11.

[0037] The storage mechanism 2 includes a storage wheel 21 and two limiting plates 22 sleeved on the storage wheel 21. Both ends of the storage wheel 21 are rotatably connected to the frame 1. The cross-sectional shape of the limiting plate 22 is a ring. One of the limiting plates 22 is fixedly connected to the storage wheel 21 by welding, and the other limiting plate 22 is detachably connected to the storage wheel 21 by screws. During use, the coiled steel strip 11 is sleeved on the storage wheel 21. Then, the limiting plate 22 is moved according to the width of the steel strip 11 so that both ends of the steel strip 11 are respectively in contact with the limiting plate 22. After that, the limiting plate 22 is fixed by screws to prevent the steel strip 11 from moving during transmission and reduce the slitting accuracy of the steel strip 11.

[0038] Refer to Figure 2 and Figure 3 , The slitting mechanism 3 includes a number of slitting components 31. The slitting components 31 are arranged in sequence and connected end to end. Adjacent two slitting components 31 are rotatably connected. In this embodiment, the number of slitting components 31 is four. The slitting component 31 includes a cutter head 311 for cutting the steel strip 11. The cutter head 311 is a circular thin sheet. An installation groove 3111 is opened in the middle of the cutter head 311. The installation groove 3111 penetrates from one side of the cutter head 311 to the other side. The cross-sectional shape of the installation groove 3111 is a rectangle. An installation shaft 312 is arranged on the cutter head 311. The virtual center line of the installation shaft 312 is perpendicular to the virtual center line of the cutter head 311. The installation shaft 312 is located in the installation groove 3111. Both ends of the installation shaft 312 are fixedly connected to the side walls of the installation groove 3111 by welding. A first rod 313 and a second rod 314 are arranged on the installation shaft 312. The length of the first rod 313 is less than the diameter of the cutter head 311. The structure and size of the first rod 313 are equal to those of the second rod 314. The middle parts of the first rod 313 and the second rod 314 are both penetrated through the installation shaft 312 and rotatably connected to the installation shaft 312. Both ends of the first rod 313 are respectively rotatably connected to the first rods 313 of adjacent two slitting components 31. Both ends of the second rod 314 are respectively rotatably connected to the second rods 314 of adjacent two slitting components 31.

[0039] Both ends of the strip dividing mechanism 3 are provided with connecting mechanisms 5. The connecting mechanisms 5 are symmetrically arranged. The connecting mechanism 5 includes a cutting knife 51 for cutting the steel strip 11 and two connecting rods 52 for connecting with the strip dividing mechanism 3. The two connecting rods 52 are rotatably connected to each other. The shape and size of the cutting knife 51 are the same as those of the cutter head 311. One end of each of the two connecting rods 52 is rotatably connected to the side of the cutting knife 51 close to the strip dividing mechanism 3. One end of a connecting rod 52 away from the cutting knife 51 is rotatably connected to the first rod 313 of the adjacent strip dividing assembly 31, and the other side of the other connecting rod 52 away from the cutting knife 51 is rotatably connected to the second rod 314 of the adjacent assembly. On one side of a cutting knife 51 away from the strip dividing assembly 31, there is a driving mechanism 6 for driving the strip dividing assembly 31 to cut the steel strip 11 and convey the steel strip 11. On the side of the other cutting knife 51 away from the strip dividing assembly 31, a connecting shaft 7 is fixedly arranged by welding. One end of the connecting shaft 7 away from the strip dividing mechanism 3 is rotatably connected to the frame 1.

[0040] The driving mechanism 6 includes a rotating assembly 61 for driving the cutter head 311 and the cutting knife 51 to rotate. The rotating assembly 61 includes a rotating tube 611 and a sliding rod 612 inserted into the rotating tube 611 and slidably connected to the rotating tube 611. One end of the sliding rod 612 is rotatably connected to the cutting knife 51. The rotating tube 611 is a hollow cylinder with a closed bottom end. The rotating tube 611 is inserted into the frame 1 and rotatably connected to the frame 1. A motor 62 is arranged at the closed end of the rotating tube 611. The output end of the motor 62 is fixedly connected to the rotating tube 611 by a key.

[0041] Refer to Figure 4 and Figure 5 As shown in, two sliding grooves 6111 are formed on the inner wall of the rotating tube 611. The number of the sliding grooves 6111 is two. The included angle formed by the extending directions of the two sliding grooves 6111 is 180 degrees. A sliding block 6122 which is fixedly arranged on the side wall of the sliding rod 612 by welding and is embedded in the sliding groove 6111 and slidably connected to the sliding groove 6111 is provided. The length of the sliding block 6122 is less than the length of the sliding rod 612. The sliding block 6122 is embedded in the sliding groove 6111. When the rotating tube 611 rotates, the rotating tube 611 will drive the sliding block 6122 to rotate, so that the sliding rod 612 and the rotating tube 611 rotate synchronously, avoiding the rotation of the sliding rod 612 in the rotating tube 611 and affecting the use of the steel strip 11 strip dividing equipment.

[0042] Refer to Figure 1 , Figure 6 and Figure 7, the driving mechanism 6 further includes a first ratchet wheel 64 and a first pawl 63 used in cooperation with the first ratchet wheel 64. The first ratchet wheel 64 is fixedly connected to the cutting knife 51 by welding. The virtual central axis of the first ratchet wheel 64 coincides with the virtual central axis of the cutting knife 51. The first pawl 63 is rotatably connected to the sliding rod 612. A receiving groove 6121 is formed in the sliding rod 612. One end of the first pawl 63 is located in the receiving groove 6121, and the other end of the first pawl 63 extends out of the receiving groove 6121. A first reset member 65 for resetting the first pawl 63 is arranged on one side of the first pawl 63. The first reset member 65 is located in the receiving groove 6121. When the motor 62 rotates forward, the first ratchet wheel 64 and the first pawl 63 are engaged, and one side of the first pawl 63 abuts against the side wall of the receiving groove 6121. When the motor 62 rotates in reverse, the first pawl 63 slides along the inner wall of the first ratchet wheel 64.

[0043] The first reset member 65 includes a telescopic rod 651 and a spring 652. The cross-sectional shape of the telescopic rod 651 is circular. One end of the telescopic rod 651 is hinged to the sliding rod 612, and the other end of the telescopic rod 651 is hinged to the middle of the first pawl 63. The spring 652 is sleeved on the movable end of the telescopic rod 651. The diameter of the spring 652 is larger than the diameter of the movable end of the telescopic rod 651 and smaller than the diameter of the fixed tube of the telescopic rod 651. One end of the spring 652 is fixedly connected to the fixed end of the telescopic rod 651 by welding.

[0044] When the motor 62 operates, the rotation of the motor 62 will drive the rotation of the rotating tube 611. Under the action of the sliding block 6122 and the sliding groove 6111, the rotation of the rotating tube 611 will drive the rotation of the sliding rod 612, and the rotation of the sliding rod 612 will drive the rotation of the first ratchet wheel 64. When the motor 62 rotates forward, the first ratchet wheel 64 meshes with the first pawl 63, and the rotation of the first pawl 63 drives the rotation of the first ratchet wheel 64. Since the first pawl 63 is fixedly connected to the cutting knife 51, the rotation of the first pawl 63 will drive the rotation of the connecting mechanism 5 and the strip dividing mechanism 3, thereby driving the rotation of the connecting shaft 7, and the strip dividing of the steel strip 11 is realized through the rotation of the cutter head 311 and the dividing knife; when the motor 62 rotates reversely, the side wall of the first ratchet wheel 64 squeezes the first pawl 63, causing the first pawl 63 to rotate. The first pawl 63 presses the spring 652 and the telescopic rod 651, so that both the spring 652 and the telescopic rod 651 are in a compressed state. When the side wall of the first ratchet wheel 64 does not squeeze the first pawl 63, due to the elastic force generated by the spring 652 being in a compressed state, under the action of the elastic force of the spring 652, the first pawl 63 is in the initial position. Under the action of the spring 652 and the telescopic rod 651, when the motor 62 rotates reversely, the first pawl 63 rotates along the inner wall of the first ratchet wheel 64 and does not drive the rotation of the first ratchet wheel 64. Since the sliding rod 612 is rotatably connected to the cutting knife 51, the strip dividing of the steel strip 11 is realized when the motor 62 rotates forward, and when the motor 62 rotates reversely, the strip dividing mechanism 3 stops operating.

[0045] Refer to Figure 2 and Figure 3 In reference to

[0046] Refer to Figure 3 and Figure 5, a second ratchet wheel 83 is rotatably arranged at one end of the mounting seat 81 away from the frame 1. The second ratchet wheel 83 is sleeved on the rotating tube 611, and the virtual center line of the second ratchet wheel 83 coincides with the virtual center line of the rotating tube 611. A receiving groove 6112 is formed in the side wall of the rotating tube 611. A second pawl 84 rotatably connected to the rotating tube 611 is arranged in the receiving groove 6112. One end of the second pawl 84 extends out of the receiving groove 6112. A second reset member 86 for resetting the second pawl 84 is arranged on the rotating tube 611. The structure of the second reset member 86 is the same as that of the first reset member 65. One end of the telescopic rod 651 of the second reset member 86 is hinged to the second pawl 84, and the other end is hinged to the rotating tube 611. A transmission member 85 for transmitting the rotation of the second ratchet wheel 83 to the moving member 82 to make the moving member 82 slide along the length direction of the sliding rod 612 is arranged on the frame 1.

[0047] The transmission member 85 includes a fixing plate 851 fixedly connected to the frame 1 by welding and a transmission shaft 852 inserted into the fixing plate 851 and rotatably connected to the fixing plate 851. A first bevel gear 853 is arranged at one end of the transmission shaft 852. The first bevel gear 853 is fixedly connected to the transmission shaft 852 by a key. A second bevel gear 854 meshing with the first bevel gear 853 is arranged on the second ratchet wheel 83. The second bevel gear 854 is sleeved on the second ratchet wheel 83 and fixedly connected to the second ratchet wheel 83 by welding. The transmission member 85 further includes a transmission rod 855 and an adjusting rod 856. The transmission rod 855 and the first bevel gear 853 are respectively located on both sides of the fixing plate 851. One end of the transmission rod 855 is rotatably connected to one end of the adjusting rod 856, and the other end of the transmission rod 855 is fixedly connected to the transmission shaft 852 by welding. The end of the adjusting rod 856 away from the transmission rod 855 is rotatably connected to the moving member 82. When the second ratchet wheel 83 rotates, the second bevel gear 854 rotates. Since the first bevel gear 853 and the second bevel gear 854 are meshed, the rotation of the second bevel gear 854 will drive the first bevel gear 853 to rotate, causing the transmission shaft 852 to rotate, thereby causing the transmission rod 855 to rotate. The rotation of the transmission rod 855 will drive the adjusting rod 856 to move, thereby driving the moving member 82 to move, realizing the movement of the moving member 82.

[0048] The moving member 82 includes two moving tubes 821. The cross-sectional shape of the moving tube 821 is rectangular. The shapes and sizes of the two moving tubes 821 are the same. The two moving tubes 821 are assembled into a cuboid. Limiting grooves 8211 are formed in the side walls of the moving tubes 821. A limiting ring 641 is fixedly arranged on the outer side of the first ratchet wheel 64 by welding. The cross-sectional shape of the limiting ring 641 is circular. The limiting ring 641 is embedded in the limiting groove 8211 and is rotatably connected to the limiting groove 8211. When installing the moving member 82 and the first ratchet wheel 64, the limiting ring 641 is embedded in the limiting groove 8211, and the two moving tubes 821 are spliced together and connected by screws, which improves the installation convenience of the moving member 82 and the first ratchet wheel 64 and facilitates the disassembly and replacement of the moving member 82 and the first ratchet wheel 64.

[0049] When the slitting size of the steel strip 11 changes, the distance between the cutter disks 311 needs to be adjusted. The rotation of the motor 62 will drive the rotation of the rotating tube 611. The rotation of the rotating tube 611 will drive the rotation of the second pawl 84. When the motor 62 rotates in reverse, the second ratchet wheel 83 and the second pawl 84 are engaged, and the first pawl 63 rotates along the inner wall of the first ratchet wheel 64. The rotation of the rotating tube 611 will drive the rotation of the second ratchet wheel 83 and will not cause the cutter disks 311 to rotate. Under the action of the transmission member 85, the moving member 82 will be driven to slide along the length direction of the sliding rod 612. Since the limiting ring 641 is embedded in the limiting groove 8211, the movement of the moving member 82 will drive the first ratchet wheel 64 to move, thereby driving the cutting knife 51 to move and causing the first rod 313 and the second rod 314 to rotate. Therefore, the distance between the cutter disks 311 can be adjusted without disassembling the cutter disks 311, which improves the working efficiency of the steel strip 11 slitting device; when the motor 62 rotates forward, the second pawl 84 rotates along the inner wall of the second ratchet wheel 83 and will not drive the second ratchet wheel 83 to rotate, realizing that the adjusting mechanism 8 stops operating when the motor 62 rotates forward and the adjusting mechanism 8 adjusts the distance between the cutter disks 311 when the motor 62 rotates in reverse.

[0050] Refer to Figure 1 and Figure 4 As shown in [relevant figure numbers], the conveying mechanism 4 is located between the storage mechanism and the slitting mechanism 3. The conveying mechanism 4 includes two rollers 41. When conveying the steel strip 11, the steel strip 11 is located between the two rollers 41. The virtual center lines of the two rollers 41 are parallel to each other. Both sides of the two rollers 41 are rotatably connected to the frame 1. The two rollers 41 are driven by gears. One end of one of the rollers 41 is belt-driven by a transmission shaft 852. When the motor 62 rotates forward, the connecting shaft 7 rotates, thereby driving the roller 41 to rotate to convey the steel strip 11, realizing the synchronous operation and linkage of the slitting mechanism 3 and the conveying mechanism 4 and reducing the manufacturing cost.

[0051] The implementation principle of a steel strip slitting device according to an embodiment of the present application is as follows: The rotation of the motor 62 will drive the rotation of the rotating assembly 61, thereby driving the rotation of the first pawl 63 and the second pawl 84 on the rotating assembly 61. When the motor 62 rotates forward, the first ratchet wheel 64 and the first pawl 63 are engaged, and the second pawl 84 rotates along the inner wall of the second ratchet wheel 83. The first pawl 63 drives the first ratchet wheel 64 to rotate, thereby driving the connection mechanism 5 and the slitting mechanism 3 to rotate. The steel strip 11 is slit by the rotation of the cutter head 311 and the slitting knife. When the motor 62 rotates reversely, the second ratchet wheel 83 and the second pawl 84 are engaged, and the first pawl 63 rotates along the inner wall of the first ratchet wheel 64. The rotation of the rotating tube 611 will drive the rotation of the second ratchet wheel 83 and will not cause the cutter head 311 to rotate. Under the action of the transmission member 85, the moving member 82 will be driven to slide along the length direction of the sliding rod 612. Since the limiting ring 641 is embedded in the limiting groove 8211, the movement of the moving member 82 will drive the first ratchet wheel 64 to move, thereby driving the cutting knife 51 to move, causing the first rod 313 and the second rod 314 to rotate. Therefore, the distance between the cutter heads 311 can be adjusted. In this embodiment, it is not necessary to disassemble the cutter head 311 for adjustment, which improves the working efficiency of the steel strip 11 slitting device.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
